Agent skills by garrytan

Router for the gstack skill suite. (gstack)

garrytan/gstack

Investigates bugs, errors and stack traces in phases and requires a root-cause hypothesis to be confirmed before any fix is written.

garrytan/gstack

Builds a weekly engineering retrospective from git history: commit counts, per-person contributions, work patterns and code quality numbers over a chosen window.

garrytan/gstack

Drives a real browser through Aside so the agent can open a page, read it, click through a flow, take screenshots and check console errors.

garrytan/gstack

Launches a visible AI-controlled Chromium window with a sidebar extension, so you can watch each agent action in a live activity feed and chat panel.

garrytan/gstack

Tests a SwiftUI app on a real iPhone connected by USB, reading the Swift source and then looping through screenshot, analysis and action to find bugs.

garrytan/gstack

Sends one prompt to Claude, GPT through the Codex CLI and Gemini, then tabulates response time, token use and cost, with an optional judged quality score.

garrytan/gstack

Checks each shell command for destructive patterns such as recursive deletes, force pushes and dropped tables, and asks before letting them run.

garrytan/gstack

Traces a factual error the user points out back to its source (a brain page, a memory file, SOUL.md or USER.md, or a hallucination) and fixes that source instead of just noting the correction.

garrytan/gbrain

Runs an evidence-first security audit of a codebase through gstack's trusted launcher, with static findings by default and isolated reproduction when enabled.

garrytan/gstack

Searches and writes a company-wide knowledge brain through the gbrain CLI, so durable decisions and facts about people, projects and history stay findable beyond one session.

garrytan/gbrain

Turns an English description or Mermaid source into a diagram set: the source, an editable .excalidraw file and rendered SVG and PNG images.

garrytan/gstack

Ingest links, articles, tweets, and ideas into the brain. An agent skill from garrytan/gbrain.

garrytan/gbrain

Locks file edits for the session to one directory by blocking Edit and Write calls anywhere else, useful when debugging or scoping a change.

garrytan/gstack

Sends what your notes already know about a topic to Perplexity, so the cited web search reports only what is new, such as entity updates or deal changes.

garrytan/gbrain

Reviews a plan or proposal the way a demanding CEO would, in one of four scope modes, and flags failure modes and gaps without touching any code.

garrytan/gstack

Migrate a brain from gbrain-base (or any pack) to gbrain-base-v2's 14-canonical-type taxonomy via gbrain onboard --check + the unify-types Minion handler.

garrytan/gbrain

Runs a YC-style office hours session that pressure-tests a product idea before any code and ends in a design document instead of an implementation.

garrytan/gstack

Switches on full safety by combining warnings before destructive commands with a block on edits outside one directory you choose, for work on production or live systems.

garrytan/gstack

Renders a markdown file into a finished PDF with margins, page numbers, a cover page, running headers, a clickable table of contents and an optional DRAFT watermark.

garrytan/gstack

Tests a site or service for bugs, fixes what it finds with one atomic commit per fix, and reports fix evidence and a ship-readiness summary at one of three depths.

garrytan/gstack

Opens a picker where you choose which cookie domains to copy from your real Chromium browser into the headless browse session, so QA can reach logged-in pages.

garrytan/gstack

Run gbrain skillpack-check to produce an agent-readable JSON health report for the gbrain install.

garrytan/gbrain

Runs the gstack CEO, design, engineering and DX review skills on a plan file in sequence and makes borderline taste decisions automatically using six stated decision principles.

garrytan/gstack

Establishes page load, Core Web Vitals and resource-size baselines, then compares before and after on every pull request to track performance trends over time.

garrytan/gstack

Calls the OpenAI Codex CLI from your agent in three modes: a pass or fail review of your diff, an adversarial attempt to break it, and open consultation.

garrytan/gstack

Reloads the most recent saved working state so you can continue a task after a break, a new session or a switch between workspaces.

garrytan/gstack

Learns about your product, studies the landscape and writes a DESIGN.md with a full design system covering type, color, layout, spacing and motion.

garrytan/gstack

Produces several AI-generated design variants for a UI idea, opens a comparison board, collects your structured feedback and iterates from there.

garrytan/gstack

Tests a product's developer experience live in a browser: follows the docs and getting-started flow, times it, captures errors and produces a scorecard.

garrytan/gstack

Writes missing documentation from scratch for a feature, a module or a whole project, organized as tutorial, how-to, reference and explanation pages.

garrytan/gstack

Scrapes the Hacker News front page and returns the top 30 stories as JSON with rank, title, link, points and comment count.

garrytan/gstack

Debugs in four phases (investigate, analyze, hypothesize, implement) under one rule: no fix is made until the root cause is found.

garrytan/gstack

Strips the DebugBridge Swift package and its debug-only hooks from an iOS app, including StateServer, DebugOverlay and generated state accessors.

garrytan/gstack

Regenerates the iOS debug bridge from the newest gstack templates, refreshing StateServer, DebugOverlay, Package.swift and typed state accessors.

garrytan/gstack

Read-only dashboard of the ship queue: which VERSION slots open PRs hold, which sibling workspaces have work about to ship, and the next slot to claim.

garrytan/gstack

Lets another AI agent drive your browser: one command creates a setup key and prints connection instructions for the remote agent.

garrytan/gstack

Reviews a plan for a developer-facing product by profiling developer personas, benchmarking rivals and scoring friction, in expansion, polish or triage mode.

garrytan/gstack

Shows which questions gstack skills ask you, lets you set per-question preferences and compares your declared style with what your behavior suggests.

garrytan/gstack

Tests a browser app, API, CLI, job, worker or webhook and writes a structured bug report with repro steps, without changing any code.

garrytan/gstack

Produces a weekly engineering retrospective from commit history, work patterns and code quality metrics, with trend tracking and per-person breakdowns.

garrytan/gstack

Extracts data from a web page through the Aside browser, using your real signed-in sessions, and returns one JSON document without changing anything.

garrytan/gstack

Detects where an app deploys, its production URL and health checks, then saves the deploy configuration in CLAUDE.md for /land-and-deploy.

garrytan/gstack

Installs the gbrain CLI, initializes a local PGLite or Supabase brain, registers it over MCP and records a per-remote trust policy for your agent.

garrytan/gstack

Takes finished code to a pull request: merges the base branch, runs tests, reviews the diff, bumps VERSION, updates the CHANGELOG, commits, pushes and opens the PR.

garrytan/gstack

Turns your latest successful /scrape run into a permanent browser skill with a script, a test and a fixture, so repeat scrapes run in about 200 ms.

garrytan/gstack

Converts a vague idea into a precise, executable spec in five phases, files it as an issue and can start an agent on it in a fresh worktree.

garrytan/gstack

Re-indexes a repository into gbrain and refreshes the agent search guidance in CLAUDE.md, safe to run again whenever search results look stale.
